WILLIAM O. VILLIAIWISON, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR OF TWO-THIRDS TO GEORGE WILLIAMSON AND JOHN D. WILLIAMSON,

OF SAME PLACE.

STEAM STEERING-ENGINE.

SPECIFICATION forming part of Letters Patent No. 276,117, dated April 1'7, 1883. Application tiled August 10, 1882. (No model.)

To all whom it may concern Be it known that I, WILLIAM G. WILLlAM- SON, a citizen of the United States, residing at Philadelphianthe countyot'Philadelphiaand 5 StateofPennsylvania,haveinventeda new and useful Improvement in Steam Steering- Englues for Vessels, of which the following is a specification.

The invention consists in the combination of 1o plain or grooved friction-wheels with a steam steering-engine, for transmitting the power of the engine for operating a ships rudder. As shown in the accompanying drawings, the engine is double, having two cylinders; but my invention can be used with a single-cylinder engine.

I do not coniine myself to an engine of any given construction, though, for the purpose of showing more clearly the nature ot' my invenzo tion, I have applied it to an engine, as illustrated iu the accompanying drawings, in which- Figure l is a perspective view of an engine and operating' device. Fig. 2 is a side eleva- -tion ot' the engine in Fig. l, and Fig. 3 is a plan View of the same.

Similar letters refer to similar parts iu the several views.

A, Fig. l, is a device on a frame, a, suitably tixed to a vessel, for operating a steam steering- 3o engine, B. Turning in bearings is a screwshaft, b, which has a handwheel, c, on its ex tension, and is fitted with a screw-nut, d. The upper side of the nut moves in a guide, c, of the housing, which serves to control its rightline motion and preventit from turning on the screw. A screw-thread is formed in the bottom edge of the nut for engaging with a worm,

f, iitted loosely on a parallel shaft, with which it turns and slides along by means of a feather. 4u A collar of the worm is embraced by a forked end of a lever, g, on a xed center. The other end, h, of the lever is in connection with a rockshaft, t, ofthe steering-engine B by means of a rod,j.

The exigirle B has a bed-plate, k, steaxncylinders l, and a steam-chest, m, from which steam is alternately admitted to the cylinders by the rock-shaft t, which receives motion through the medium ofthe rod j ofthe device A.

l2are frictionwheels,eitherplain or grooved,

on shafts o o', in suitable bearings of the housings p, fixed to the bed-plate. The bearings q of the shafts o have-a longitudinal motion in guides r, formed in the housings. The motion of the pistons is communicated to the frictionwheels l 2 by connecting-rods s, which are coupled to the cranks or crank-wheels tof' the shaft o and to the cross-heads u.

As shown in Fig. 3 and its supplemental views, c are rock-shafts, whose eccentrics and 6o straps fw turn in seats formed in the housings. They are attached to the movable boxes q of the shaft o', and have a simultaneous action, eli'ected by cranks to and side rods,w2,hy which they are connected with the cranks of a horizontal shaft, w, placed beneath. The movement of these rock-shafts is governed by a weighted lever, cc, attached to either of them, and within reach of the steersmau through a. rope, fr', by which the shaft o can be slipped 7o forward or backward and the friction-wheels l 2 connected or disconnected. A tension-pulley, y, on an adjustable. arm of the shaft 0 is operated by a block and rope, y', for tightening the rope or belt y2, leading from the pulley yf on the shaft o to the hand steering-wheel yt.

It serves for a variable pressure in transmitting motion to the tiller-chains.

When the wheel cis turned for moving the rudder in any required direction, rotary mo- 8o tion is imparted to the screw b, by which the nut d is moved in a consequent direction and the lever g vibrated, which causes the rodj to work the rock-shaft for alternately admitting steam to the cylinders l through the valve. The crank-wheels simultaneously receive the motion of the pistons and put the wheels l 2 in motion. The cord or belt y2 from the Wheel ya on the shaft o to the hand-wheel g4 sets in motion the tiller-chains g5, which work the 9o ships rudder.

The eii'ort of the engine is suspended for retaining the rudder in a required position by drawing the rope x', which, by lifting the lever w, turns the eccentrics to, Fig. 3, in their seats. The boxes q, partaking of the motion ofthe eccentrics, withdraw the shaft o and remove the friction-wheel 2 from its contact with the wheel l, which drives it.

When it is desired to change the running of roo the engine for shifting the position ofthe ships rudder, the wheel c is moved in 2L direction contrary to that just described, which causes the link j andthe rock-shaft t' to movet :valve to its proper position for reversing t direction of the motion of the engine.

What I claim as my invention, and desire secure by Letters Patent, is-

l. A steering-engine having friction-wheels as elements in its construction, combined with an independent direct hand steering-drum and means for communicating the rotary motion the engine to said independent drum, substantially as set forth.

2. A steering-engine having friction-wheels x5 he and sheaves or rope-pulleys entering into its he l structure, combined with an independent direct hund steering-drum l and a rope for transto Initting rotary motion from the engine to said independent drum, substantially as set forth. zo
